I have a 1641cc rail buggy with an off-road racing exhaust. I've read online that silver lake Michigan requires you to have a muffle and spark arrestor to ride on the dunes or in Michigan parks period. They also state that the max noise level is 94 dBa at 20 inches. Here is the site with that info http://www.michigan.gov/dnr/0,1607,7-15 ... --,00.html
I have a 10 inch spark arrestor with a built in muffler that slips onto my pipes and was wondering if this was enough to past their regulations. Here is the spark arrestor i have. http://www.jbugs.com/product/3736.html? ... -arresters
Please someone explain to me how loud 94 dBa is and whether or not buggy will make it in the park.
